Why the structure v is not stable in resonance?...

but their is = bond - bond conjugation ....is present so why not it is a resonating structure

here we are talking the stability of free radical so we will check the factors which stabilised the free radical

but why only here written that resonance i>ii then mention about hyperconjugation

in these structures free radical is involved in resonance so we are including these in resonance

in resonance =bond and - bond is one type of conjugation ....so why not it is a resonating structure

but u told that free redical is not involved in resonance

yes, here structure is aromatic and stable due to 6pi electrons. so free radical is not involved in aromatic system as it is already stabilised. sp free radical is unstable

why structure v is not an aromatic structure

Yes, Structure V is aromatic

hope you got it.

structure v is a resonating structure or not

yes it is resonating structure, and aromatic

so why not here mention about the resonance of structure v

so why u told that structure v is not resonating inur first comment

listen, you are correct and we can write here resonance but this resonance doesn't effect stability of free radical because free radical is localised and not involved in resonance so we don't include resonance factor in str V

yes i didn't mention str V as resonating str. because we are talking about free radical and it doesn't involve resonance so why shoud mention free radical as resonating structure?
